ABSTRACT:
A pressure sensitive adhesive is prepared by the polymerization of an appropriate acrylic ester formulation of the type that includes an ethylenically unsaturated monomer having a polar group, and at least part of such polymerization is accomplished by photopolymerization using a source of ultraviolet radiation that provides a substantial portion of its ultraviolet radiation in the wavelength band of from about 280 to about 350 nm and a light intensity at the surface of the formuation being polymerized of no more than about 4.0 milliwatts/cm.sup.2.
